<p>I am sending out a manila envelope with 4 sheets of paper inside. Is a first class stamp okay for this? Or should I put two?</p>
<p>Sorry if this sounds like a common sense question, I do not usually send out mail with large envelopes.</p>
<p>It depends. Take it to the post office and have it weighed. 4 pages is close to one ounce. It all depends on the size (weight) of the envelope whether you exceed one ounce. Two stamps would be the safe way to go.</p>
<p>Correction: I will be sending out 6 sheets of paper.</p>
<p>Are two stamps still good?</p>
<p>No.</p>
<p>The postal rates for large manila envelopes are different from those for regular envelopes. A 9x12 envelope -- even with NO papers inside -- requires $.83 in postage.</p>
<p>Here's the link to the USPS rate calculator:</p>
<p>Postage</a> Price Calculator</p>
<p>He didn't say it was a "large" manila envelope. He just said it was manila.</p>
<p>I think 5 sheets tip the scale.</p>
<p>check this site: [postage</a> rates](<a href=“http://www.currentpostagerates.org%22%5Dpostage”>http://www.currentpostagerates.org), it says if your envelope is more than 11 1/2" x 6 1/8" regardless of weigh then it is a “large envelope” and will cost more than a regular one (almost twice as much, even at just 1 ounce)</p>
